*frevvo for Confluence is no longer available in v11.0+.
The following security vulnerabilities have been addressed as follows:
Man in the middle - This has to do with executing the CGI Servlet. This servlet is disabled in the frevvo Apache tomcat distribution. Customers who choose to enable the servlet are responsible for ensuring security viz. adding filter etc.
Version Disclosures - Resolved by configuring the ErrorReportValve in \frevvo\tomcat\conf\server.xml file (in the Host section) as described in this Apache tomcat website. The parameter that needs to be modified is:
X-Frame-Options Header Not Set - Resolved by modification at the tomcat level. In-house customers can uncomment the HttpHeaderSecurityFilter provided in the tomcat web.xml. The filter is documented here. Specify the appropriate X-Frame-Options value in the antiClickJackingOption parameter - (SAMEORIGIN or ALLOW-FROM).
Setting this parameter to SAMEORIGIN may interfere when embedding frevvo forms/flows in your website. Use ALLOW-FROM instead.
